Characterization And Automated Classification Of Sentences In The Biomedical Literature: A Case Study For Biocuration Of Gene Expression And Protein Kinase Activity., Daniela Raciti, Kimberly M Van Auken, Valerio Arnaboldi, Christopher J Tabone, Hans-Michael Muller, Paul W Sternberg

Faculty Research 2025

Biological knowledgebases are essential resources for biomedical researchers, providing ready access to gene function and genomic data. Professional, manual curation of knowledgebases, however, is labour-intensive and thus high-performing machine learning (ML) methods that improve biocuration efficiency are needed. Here, we report on sentence-level classification to identify biocuration-relevant sentences in the full text of published references for two gene function data types: gene expression and protein kinase activity. We performed a detailed characterization of sentences from references in the WormBase bibliography and used this characterization to define three tasks for classifying sentences as either (i) fully curatable, (ii) fully and partially …

Objective: Coronary atherosclerosis (CAD) is characterized by arterial intima lipid deposition, chronic inflammation, and fibrous tissue proliferation, leading to arterial wall thickening and lumen narrowing. As the primary cause of coronary heart disease and acute coronary syndrome, CAD significantly impacts global health. Recent genetic studies have demonstrated CAD's polygenic and multifactorial nature, providing molecular insights for early diagnosis and risk assessment. This review analyzes recent advances in CAD-related genetic markers and evaluates their diagnostic potential, focusing on their applications in diagnosis and risk stratification within precision medicine.

Methods: We conducted a systematic review of CAD genomic studies from PubMed and …

Feasibility Of Ex Vivo Ligandomics, Prabuddha Waduge, Remya Ammassam Veettil, Bojun Zhang, Chengchi Huang, Hong Tian, Wei Li

Faculty, Staff and Students Publications

We developed ligandomics for the in vivo profiling of vascular ligands in mice, discovering secretogranin III (Scg3) as a novel angiogenic factor that selectively binds to retinal vessels of diabetic but not healthy mice. This discovery led to the development of anti-Scg3 therapy for ocular vasculopathies. However, in vivo ligandomics requires intracardial perfusion to remove unbound phage clones, limiting its use to vascular endothelial cells (ECs). To extend ligandomics to non-vascular cells, we investigated ex vivo ligandomics. We isolated ECs and retinal ganglion cells (RGCs) from diabetic and healthy mouse retinas by immunopanning. We quantified the binding of clonal phages …

Differences In Risk Appraisal And Neural Activity In Adolescents With A History Of Misconduct, Elizabeth S Escalante, Jessica S Flannery, Michael T Perino, Eva H Telzer

2020-Current year OA Pubs

While much of the prior work examining the behavioural and neural mechanisms of adolescent risk taking has focused on community samples, less is known about whether these mechanisms apply to adolescents engaging in high levels of risky behaviour. The current study examines behavioural and neural differences between adolescents with (N = 24) and without (N = 35) a history of misconduct using a risk perception questionnaire and risk-taking fMRI task. Adolescents with a history of misconduct perceived fewer negative consequences of risk relative to positive consequences and exhibited altered neural tracking of risk and reward in the nucleus accumbens. Specifically, …

Purpose: Biliary tract cancers, which are rare and aggressive malignancies, are rich in clinically actionable molecular alterations. A major challenge in the field is the paucity of clinically relevant biliary tract cancer models that recapitulate the diverse molecular profiles of these tumors. The purpose of this study was to curate a collection of patient-derived xenograft (PDX) models that reflect the spectrum of genomic alterations present in biliary tract cancers to create a resource for modeling precision oncology.

Experimental design: PDXs were derived from biliary tract cancer samples collected from surgical resections or metastatic biopsies. Alterations present in the PDXs were …

Innervation Of Human Intestinal Organoids, Rachel C Bordelon, Madushani Herath, Allison L Speer

Faculty, Staff and Student Publications

The complexity of intestinal cytoarchitecture and function poses significant challenges for the creation of the bioengineered small intestine. Techniques for generating human intestinal organoids (HIOs) resembling human small intestine have been previously reported. HIOs contain epithelium and mesenchyme but lack other critical components of functional intestine such as the enteric nervous system (ENS), immune cells, vasculature, and microbiome. Two independent research groups have published distinct methods to innervate HIOs with an ENS. Here we discuss a unique method of incorporating the ENS into an HIO-derived bioengineered small intestine, which utilizes components of these prior reports to optimize progenitor cell identity …

Arthritis leads to bone erosion due to an imbalance between osteoclast and osteoblast function. Our prior investigations revealed that the Ca2+-selective ion channel, Orai1, is critical for osteoclast maturation. Here, we show that the small-molecule ELP-004 preferentially inhibits transient receptor potential canonical (TRPC) channels. While ELP-004 minimally affected physiological RANKL-induced osteoclast maturation in murine bone marrow- and spleen-derived myeloid cells (BMSMCs) and human PBMC-derived cells, it potently interfered with osteoclast maturation driven by TNFα or LTB4. The contribution of TRPC channels to osteoclastogenesis was examined using BMSMCs derived from TRPC4-/- or TRPC(1-7)-/- mice, again revealing preferential interference with osteoclastogenesis driven …

Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes. NKAPL binds to promoter-associated nascent transcripts and co-localizes with DNA-RNA hybrid R-loop structures at GAA-rich loci to enhance R-loop formation and facilitate Pol II pause-release. NKAPL depletion prolongs Pol II pauses and stalls the SOX30/HDAC3 transcription initiation complex …

Neutralizing antibody titer has been a surrogate endpoint for guiding COVID-19 vaccine approval and use, although the pandemic's evolution and the introduction of variant-adapted vaccine boosters raise questions as to this surrogate's contemporary performance. For 985 recipients of an mRNA second bivalent or monovalent booster containing various Spike inserts [Prototype (Ancestral), Beta, Delta, and/or Omicron BA.1 or BA.4/5] in the COVAIL trial (NCT05289037), titers against 5 strains were assessed as correlates of risk of symptomatic COVID-19 ("COVID-19") and as correlates of relative (Pfizer-BioNTech Omicron vs. Prototype) booster protection against COVID-19 over 6 months of follow-up during the BA.2-BA.5 Omicron-dominant period. …

Viroporin Activity Is Necessary For Intercellular Calcium Signals That Contribute To Viral Pathogenesis, J Thomas Gebert, Francesca J Scribano, Kristen A Engevik, Ethan M Huleatt, Michael R Eledge, Lauren E Dorn, Asha A Philip, Takahiro Kawagishi, Harry B Greenberg, John T Patton, Joseph M Hyser

Faculty, Staff and Students Publications

Viruses engage in a variety of processes to subvert host defenses and create an environment amenable to replication. Here, using rotavirus as a prototype, we show that calcium conductance out of the endoplasmic reticulum by the virus encoded ion channel, NSP4, induces intercellular calcium waves that extend beyond the infected cell and contribute to pathogenesis. Viruses that lack the ability to induce this signaling show diminished viral shedding and attenuated disease in a mouse model of rotavirus diarrhea. This implicates nonstructural protein 4 (NSP4) as a virulence factor and provides mechanistic insight into its mode of action. Critically, this …

Phosphate and tensin homolog hamartoma tumor syndrome, DICER1-related tumor predisposition, and tuberous sclerosis complex are rare conditions, which each increases risk for distinct spectra of benign and malignant neoplasms throughout childhood and adulthood. Surveillance considerations for each of these conditions focus on patient and family education, early detection, and multidisciplinary care. In this article, we present updated surveillance recommendations and considerations for children and adolescents with phosphate and tensin homolog hamartoma tumor syndrome, DICER1-related tumor predisposition, and tuberous sclerosis complex and provide suggestions for further research in each of these conditions.

Barcoded Sars-Cov-2 Viruses Define The Impact Of Duration And Route Of Exposure On The Transmission Bottleneck In A Hamster Model, Reed Trende, Tamarand L Darling, Tianyu Gan, David Wang, Adrianus C M Boon

2020-Current year OA Pubs

The transmission bottleneck, defined as the number of viruses shed from one host to infect another, is an important determinant of the rate of virus evolution and the level of immunity required to protect against virus transmission. Despite its importance, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission bottleneck remains poorly characterized. We adapted a SARS-CoV-2 reverse genetics system to generate a pool of >200 isogenic SARS-CoV-2 viruses harboring specific 6-nucleotide barcodes, infected donor hamsters with this pool, and exposed contact hamsters to paired infected donors, varying the duration and route of exposure. Following exposure, the nasal turbinates, trachea, …

Hiv Associated Epigenetic Trends And Chronic Diseases: Insights Into The Hidden Burden Of Chronic Infection, Courtney G. Wallace, Zachary Capriotti, Zachary Klase

Kimmel Cancer Center Faculty Papers

Human Immunodeficiency Virus (HIV) remains a major health challenge despite dramatic advances in treatment and prevention. People living with HIV (PLWH) continue to experience high rates of non-AIDS comorbidities, including cardiovascular, renal, pulmonary, oncologic, and neurocognitive disorders. These conditions persist under viral suppression, underscoring the lasting biological impact of infection. Epigenetic dysregulation has emerged as a key driver of these outcomes. HIV integration, viral proteins, chronic inflammation, and ART exposure have all been reported to alter DNA methylation, histone modifications, transcription factor networks, and noncoding RNA regulation. These changes extend beyond infected cells, reprogramming uninfected immune and tissue compartments. Long-lived …

N-Glycosylation In The Serpin Domain Of The C1-Esterase Inhibitor In Hereditary Angioedema, Zhen Ren, John Bao, Shuangxia Zhao, Nicola Pozzi, H. James Wedner, John P. Atkinson

2020-Current year OA Pubs

Hereditary angioedema is an autosomal dominant disorder caused by defects in C1-esterase inhibitor (C1-INH), resulting in poorly controlled activation of the kallikrein-kinin system and bradykinin overproduction. C1-INH is a heavily glycosylated protein in the serine protease inhibitor (SERPIN) family, yet the role of these glycosylation sites remains unclear. To elucidate the functional impact of N-glycosylation in the SERPIN domain of C1-INH, we engineered 4 sets consisting of 26 variants at or near the N-linked sequon (NXS/T). Among these, 6 are reported in patients with hereditary angioedema and 5 are known C1-INH variants without accessible clinical histories. We systematically evaluated their …

Discontiguous Recurrences Of Idh-Wildtype Glioblastoma Share A Common Origin With The Initial Tumor And Are Frequently Hypermutated, Malcolm F Mcdonald, Sricharan Gopakumar, Tareq A Juratli, Ilker Y Eyüpoglu, Ganesh Rao, Jacob J Mandel, Ali Jalali

Faculty, Staff and Students Publications

Glioblastoma is the deadliest primary brain tumor, largely due to inevitable recurrence of the disease after treatment. While most recurrences are local, patients rarely present with a new discontiguous focus of glioblastoma. Little is currently known about the genetic profile of discontiguous recurrences. In our institutional database, we identified 22 patients with targeted exome sequencing of pairs of initial and recurrent IDH-wildtype glioblastoma. Recurrences were classified as contiguous or discontiguous based on the presence or absence of T2 FLAIR signal connection to the initial site of disease on MRI. Exome analysis revealed shared driver and passenger mutations between discontiguous recurrences …

Engineered probiotics are an emerging platform for in situ delivery of therapeutics to the gut. Herein, we developed an orally administered, yeast-based therapeutic delivery system to deliver next-generation immune checkpoint inhibitor (ICI) proteins directly to gastrointestinal tumors. We engineered Saccharomyces cerevisiae var. boulardii (Sb), a probiotic yeast with high genetic tractability and innate anticancer activity, to secrete "miniature" antibody variants that target programmed death ligand 1 (Sb_haPD-1). When tested in an ICI-refractory colorectal cancer (CRC) mouse model, Sb_haPD-1 significantly reduced intestinal tumor burden and resulted in significant shifts to the immune cell profile and microbiome composition. This oral therapeutic platform …

Introduction: The annual prevalence of elder mistreatment (EM) in cognitively intact older adults is estimated to be 11%, yet the annual prevalence in older adults with Alzheimer's disease and related dementias (AD/ADRD) is estimated to be as high as 75%. Associated with a decrease in quality of life and increase in risk of mortality, EM represents a significant public health burden. Home-based primary care (HBPC) providers are uniquely positioned to address the critical need for robust EM screening and reporting, especially among individuals with AD/ADRD. This protocol seeks to adapt the Detection of Elder mistreatment Through Emergency Care Technicians (DETECT) …

Electrostatic Force-Enabled Microneedle Patches That Exploit Photoredox Catalysis For Transdermal Phototherapy, Hang Zhang, Wen-Chuan Xie, Yuhang Yao, Zi-Yi Tang, Wen-Xiu Ni, Bingwu Wang, Song Gao, Jonathan L Sessler, Jun-Long Zhang

Faculty, Staff and Student Publications

Microneedle patches for topical administration of photodynamic therapy (PDT) sensitizers are attractive owing to their safety, selectivity, and noninvasiveness. However, low-efficiency photosensitizer delivery coupled with the limitations of the hypoxic tumor microenvironment remains challenging. To overcome these issues, we developed an effective microneedle patch based on intermolecular electrostatic interactions within a photosensitizer matrix containing a zinc-containing porphyrin analogue, ZnBP (w). This design improved the mechanical strength of the microneedle patch and enhanced the photosensitizer loading efficiency in aqueous environments. A key feature of the system is efficient electron transfer between ZnBP (w) and NADH upon photoirradiation. Electrostatic interactions between ZnBP …

A Case For Broadening Our View Of Mechanism In Developmental Biology, B Duygu Özpolat, Swathi Arur, Mansi Srivastava

Faculty, Staff and Student Publications

Developmental biologists can perform studies that describe a phenomenon (descriptive work) and/or explain how the phenomenon works (mechanistic work). There is a prevalent perception that molecular/genetic explanations achieved via perturbations of gene function are the primary means of advancing mechanistic knowledge. We believe this to be a limited perspective, one that does not effectively represent the breadth of work in our field. We surveyed a representative and diverse group of colleagues to share their views on what it takes to infer mechanism. Here, we briefly examine the factors that have shaped the dominant view of mechanism, summarize responses to the …

Foxr2 Targets Lhx6+/Dlx+ Neural Lineages To Drive Central Nervous System Neuroblastoma, Selin Jessa, Antonella De Cola, Bhavyaa Chandarana, Michael Mcnicholas, Steven Hébert, Adam Ptack, Damien Faury, Jessica W Tsai, Andrey Korshunov, Timothy N Phoenix, Benjamin Ellezam, David T W Jones, Michael D Taylor, Pratiti Bandopadhayay, Manav Pathania, Nada Jabado, Claudia L Kleinman

Central nervous system neuroblastoma with forkhead box R2 (FOXR2) activation (NB-FOXR2) is a high-grade tumor of the brain hemispheres and a newly identified molecular entity. Tumors express dual neuronal and glial markers, leading to frequent misdiagnoses, and limited information exists on the role of FOXR2 in their genesis. To identify their cellular origins, we profiled the transcriptomes of NB-FOXR2 tumors at the bulk and single-cell levels and integrated these profiles with large single-cell references of the normal brain. NB-FOXR2 tumors mapped to LHX6+/DLX+ lineages derived from the medial ganglionic eminence, a progenitor domain in the ventral telencephalon. In vivo prenatal …

Introducing "Identification Probability" For Automated And Transferable Assessment Of Metabolite Identification Confidence In Metabolomics And Related Studies., Thomas O Metz, Christine H Chang, Vasuk Gautam, Afia Anjum, Siyang Tian, Fei Wang, Sean M Colby, Jamie R Nunez, Madison R Blumer, Arthur S Edison, Oliver Fiehn, Dean P Jones, Shuzhao Li, Edward T Morgan, Gary J Patti, Dylan H Ross, Madelyn R Shapiro, Antony J Williams, David S Wishart

Faculty Research 2025

Methods for assessing compound identification confidence in metabolomics and related studies have been debated and actively researched for the past two decades. The earliest effort in 2007 focused primarily on mass spectrometry and nuclear magnetic resonance spectroscopy and resulted in four recommended levels of metabolite identification confidence─the Metabolite Standards Initiative (MSI) Levels. In 2014, the original MSI Levels were expanded to five levels (including two sublevels) to facilitate communication of compound identification confidence in high resolution mass spectrometry studies. Further refinement in identification levels have occurred, for example to accommodate use of ion mobility spectrometry in metabolomics workflows, and alternate …

Neutrophil Extracellular Traps Promote Pre-Metastatic Niche Formation In The Omentum By Expanding Innate-Like B Cells That Express Il-10, Wonjae Lee, Song Yi Ko, Hironari Akasaka, Melanie Weigert, Ernst Lengyel, Honami Naora

Faculty, Staff and Student Publications

Disseminated cancer cells in the peritoneal fluid often colonize omental fat-associated lymphoid clusters but the mechanisms are unclear. Here, we identify that innate-like B cells accumulate in the omentum of mice and women with early-stage ovarian cancer concomitantly with the extrusion of chromatin fibers by neutrophils called neutrophil extracellular traps (NETs). Studies using genetically modified NET-deficient mice, pharmacologic inhibition of NETs, and adoptive B cell transfer show that NETs induce expression of the chemoattractant CXCL13 in the pre-metastatic omentum, stimulating recruitment of peritoneal innate-like B cells that in turn promote expansion of regulatory T cells and omental metastasis through producing …

Nerves At Play: The Peripheral Nervous System In Extracranial Malignancies, Paola D Vermeer, Anthony C Restaino, Jeffrey L Barr, Dan Yaniv, Moran Amit

Faculty, Staff and Student Publications

The exponential growth of the cancer neuroscience field has shown that the host's immune, vascular, and nervous systems communicate with and influence each other in the tumor microenvironment, dictating the cancer malignant phenotype. Unraveling the nervous system's contributions toward this phenotype brings us closer to cancer cures. In this review, we summarize the peripheral nervous system's contributions to cancer. We highlight the effects of nerve recruitment and tumor innervation, the neuro-immune axis, glial cell activity, and neural regulation on cancer development and progression. We also discuss harnessing the neural control of peripheral cancers as a potential therapeutic approach in oncology. …

Pancreatic ductal adenocarcinoma (PDAC) resists conventional chemo/radiation and immunotherapy. In PDAC, oncogenic KRAS (KRAS*) drives glycolysis in cancer cells to consume available glucose and produce abundant lactate, creating profound immune suppression in the tumor microenvironment. Here, we combined KRAS* inhibition with agents targeting the major arms of the immunity cycle: CXCR1/2 inhibitor for myeloid cells, antagonistic anti-LAG3 antibody for T cells, and agonistic anti-41BB antibody for dendritic cells. This combination elicited robust anti-tumor regression in iKPC mice bearing large autochthonous tumors. While untreated mice succumbed within 3 weeks, sustained treatment led to durable complete tumor regression and prolonged survival in …

Soluble Herpes Virus Entry Mediator And Type Ii/Iii Interferons Are Upregulated In Primary Biliary Cholangitis, Yooyun Chung, Hio Lam Phoebe Tsou, Michael A Heneghan, Shilpa Chokshi, Antonio Riva

Peninsula Medical School

Bacterial translocation-induced inflammation and immune dysfunction are recognised factors contributing to the pathogenesis of primary biliary cholangitis (PBC). However, the specific involvement of interferons (IFNs) and soluble checkpoints (sol-CRs) in shaping the immune landscape in PBC patients remains unexplored. Furthermore, the influence of ursodeoxycholic acid (UDC) on these immune mediators is unknown. Twenty-eight cytokines and 14 sol-CRs were quantified by Luminex assays in plasma samples from 64 PBC patients and 10 healthy controls (HCs). D-lactate was measured as a marker of bacterial translocation. The PBC subgroups were: 24 UDC responders (UDCRs), 18 UDC non-responders (UDCNRs) and 22 patients with end-stage …

Lipid nanoparticles (LNPs) for mRNA delivery have advanced significantly, but LNP-mediated DNA delivery still faces clinical challenges. This study compared various LNP formulations for delivering DNA-encoded biologics, assessing their expression efficacy and the protective immunity generated by LNP-encapsulated DNA in different models. The LNP formulation used in Moderna's Spikevax mRNA vaccine (LNP-M) demonstrated a stable nanoparticle structure, high expression efficiency, and low toxicity. Notably, a DNA vaccine encoding the spike protein, delivered via LNP-M, induced stronger antigen-specific antibody and T cell immune responses compared to electroporation. Single-cell RNA sequencing (scRNA-seq) analysis revealed that the LNP-M/pSpike vaccine enhanced CD80 activation signaling …
